A genus of aquatic plants, also known as water buttercups, with delicate submerged and floating leaves.
From Greek 'batrachos' (frog) + genus name ending '-ium'. The plant was named for its association with wet, frog-inhabiting habitats.
Batrachium plants thrive in the same cold streams where frogs live, and they're so sensitive to water quality that they're used as indicators of pristine freshwater ecosystems!
